Computer architecture theory defines processor performance through the interplay of instruction set architecture (ISA), micro-architecture, and memory hierarchy to optimize execution time and throughput while managing power constraints. The core mechanism involves decomposing computational tasks into modular units—such as ALUs for arithmetic operations, registers, and pipelines—to minimize Critical Path delays and mitigate hazards like structural or data conflicts via forwarding and out-of-order execution. This theoretical framework operates within the domain of computer engineering to establish formal boundaries between hardware implementation strategies (e.g., RISC logic) and software compilation requirements (CPI optimization), ensuring that system design adheres to fundamental principles of hierarchical memory access patterns and parallel instruction processing.
